Heavy weekend rain caused murky water to pool along the north end of the Margate beach between the under-construction dunes and the bulkhead. Residents have begun calling it "Lake Christie," Philly.com said.

City commissioners will convene Wednesday to discuss their options.

The Army Corps of Engineers said it will work with state officials to pump the water out of the basin and over the dunes, the report said.

A Corps spokesman told the website the water isn't being filtered as planned.

Residents gathered Monday to voice their displeasure about the state of the beach.

Dune replenishment began in late June and is expected to conclude in the fall. It's being done in 1,000 foot sections. When it's complete, Margate's beaches will be 100 feet wide and contain dunes 13 feet tall.
